A photon is an elementary particle and the smallest packet of energy of electromagnetic radiation, such as light or X-rays.
Das Photon überträgt seine Energie auf ein Elektron.
The photon transfers its energy to an electron.

'Photon' is a technical term from physics. The word is especially common in scientific and popular science texts in connection with quantum physics, electromagnetic radiation, and measurements.
Im Experiment wurde die Energie jedes Photons genau gemessen.
The energy of each photon was measured precisely in the experiment.
Common collocations include 'ein Photon emittieren' (to emit a photon), 'ein Photon absorbieren' (to absorb a photon), and 'ein Photon nachweisen' (to detect a photon). The energy or movement of a photon is also often described.
Der Detektor konnte ein einzelnes Photon nachweisen.
The detector was able to detect a single photon.
Words such as 'Elektron' (electron), 'Detektor' (detector), 'Energieübertragung' (energy transfer), and 'Wellenlänge' (wavelength) usually indicate that 'Photon' is being used in a physics or technical context.
Je kürzer die Wellenlänge ist, desto mehr Energie trägt ein einzelnes Photon.
The shorter the wavelength, the more energy a single photon carries.
